How to retrive HTML Content from a given URL with VB 2008

[cardei]

Hi, I try to retrieve html content from a web page with VB .net

I used this code (console app) that I find on internet :

 
Imports System
Imports System.Net
Imports System.IO
Module Module1
 
  Sub Main()
        Dim sURL As String
        sURL = "http://www.checkmytrip.com"
 
        Dim wrGETURL As WebRequest
        wrGETURL = WebRequest.Create(sURL)
 
        Dim myProxy As New WebProxy("myproxy", 80)
        myProxy.BypassProxyOnLocal = True
 
        'wrGETURL.Proxy = myProxy
        wrGETURL.Proxy = WebProxy.GetDefaultProxy()
 
        Dim objStream As Stream
        objStream = wrGETURL.GetResponse.GetResponseStream()
 
        Dim objReader As New StreamReader(objStream)
        Dim sLine As String = ""
        Dim i As Integer = 0
 
        Do While Not sLine Is Nothing
            i += 1
            sLine = objReader.ReadLine
            If Not sLine Is Nothing Then
                Console.WriteLine("{0}:{1}", i, sLine)
            End If
        Loop
 
        Console.ReadLine()
 
    End Sub
 
End Module

It's work fine in console mode but when I paste it in my app the app is crash or stop responding.

I replaplace the line 30,

Console.WriteLine("{0}:{1}", i, sLine)

with

textbox1.text = textbox1.text & sline

and I deleted the line 34.

I need to extract some data from a given URL to use it later in my app.

If somebody can help me??

Sory for my english! :)

Thanks.
